O-ethyl S-2-pyridyl carbonothioate, also known as EPTC or S-ethyl dipropylthiocarbamate, is a widely used herbicide belonging to the thiocarbamate class. It is primarily employed for pre-emergence and early post-emergence control of various annual grasses and broadleaf weeds in crops such as corn, cotton, and soybeans. EPTC works by inhibiting the growth of weeds by disrupting their photosynthesis process, ultimately leading to their death. The chemical has a molecular formula of C10H16NOS2 and is characterized by its white crystalline appearance. It is soluble in water and has a relatively low vapor pressure, which contributes to its effectiveness as a soil-applied herbicide. However, due to its potential environmental and health concerns, its use is regulated in many countries, and alternative, more environmentally friendly herbicides are being developed.

Check Digit Verification of cas no

The CAS Registry Mumber 2244-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2244-49:
(6*2)+(5*2)+(4*4)+(3*4)+(2*4)+(1*9)=67
67 % 10 = 7
So 2244-49-7 is a valid CAS Registry Number.

Conversion of Hydroxyl Groups in Alcohols to Other Functional Groups with N-Hydroxy-2-thiopyridone, and Its Application to Dialkylamines and Thiols

Togo, Hideo,Fujii, Misa,Yokoyama, Masataka

, p. 57 - 67 (2007/10/02)

The radical decarboxylation reaction of N-alkoxyoxalyloxy-2-thiopyridone which was prepared by the reaction of alcohol, oxalyl chloride, and N-hydroxy-2-thiopyridone was studied both in the absence and presence of olefinic compounds.The same reactions with olefinic and acetylenic alcohols gave the corresponding lactone derivatives.On the other hand the unsymmetrical alkyl 2-pyridyl disulfides were obtained by the same reaction with aliphatic thiols.
